目的探讨常规超声与超声弹性成像诊断甲状腺良恶性肿瘤的临床价值。方法选取2010年4月至2014年9月间鄂东医疗集团黄石市中心医院收治的91例甲状腺结节患者,共99个结节,均采用常规超声和超声弹性成像检查。以甲状腺细针穿刺细胞学诊断为标准,比较图像变化及敏感性等。结果良性甲状腺结节61个,恶性甲状腺结节38个,其中恶性以乳头状癌最常见(94.7%),良性以滤泡增生结节常见(83.6%)。常规超声灵敏度、特异性和准确性分别为72.2%(26/36)、81.0%(51/63)和77.8%(77/99),超声弹性成像灵敏度、特异性和准确性分别为85.7%(30/35)、87.5%(56/64)和86.9%(86/99),常规超声联合超声弹性成像灵敏度、特异性和准确性分别为94.6%(35/37)、95.2%(59/62)和94.9%(94/99),常规超声联合超声弹性成像和常规超声或超声弹性成像任一单项比较,差异均有统计学意义(均P<0.05)。常规超声良恶性结节在形态、边界、后方衰减、钙化、血流分支和走形上比较,差异有统计学意义(P<0.05),而在内部回声、内部回声均匀度、供血情况和阻力指数等方面比较,差异无统计学意义(P>0.05);弹性成像在各个等级上差异均有统计学意义(均P<0.05)。结论常规超声与超声弹性成像检测对判断甲状腺肿瘤良恶性临床价值高。
Objective To investigate the clinical value of routine ultrasound and ultrasound elastography in the diagnosis of benign and malignant thyroid tumors. Methods Ninety-one nodules of thyroid nodules, which were treated in Huangshi Central Hospital of East Hubei Province from April 2010 to September 2014, were selected. All of them were examined by conventional ultrasound and ultrasound elastography. Thyroid fine needle aspiration cytology as the standard to compare changes in image and sensitivity. Results There were 61 benign thyroid nodules and 38 malignant thyroid nodules, of which malignant papillary carcinoma was the most common (94.7%) and benign follicular hyperplasia nodules were common (83.6%). The sensitivity, specificity and accuracy of conventional ultrasound were 72.2% (26/36), 81.0% (51/63) and 77.8% (77/99) respectively. The sensitivity, specificity and accuracy of ultrasound elastography were 85.7% The sensitivity, specificity and accuracy of conventional ultrasound combined with ultrasound elastography were 94.6% (35/37), 95.2% (59/62), 87.5% (56/64) and 86.9% (86/99) ) And 94.9% (94/99) respectively. There was significant difference between conventional ultrasound combined with ultrasound elastography and conventional ultrasound or ultrasound elastography (all P <0.05). The difference of morphology, borderline, posterior attenuation, calcification, blood flow branch and shape in conventional ultrasound was statistically significant (P <0.05), but there was no significant difference in internal echo, internal echo uniformity, blood supply and resistance Index and other aspects, the difference was not statistically significant (P> 0.05); elastography at all levels were statistically significant differences (P <0.05). Conclusion Conventional ultrasound and elastography detection of benign and malignant thyroid tumor high clinical value.
